  • "Show me a man who makes no mistakes, and I will show you a man who has done nothing."—LIEBIG. In this little volume the author gives but his own personal opinions upon the subjects discussed, and although the sentiments are expressed with an assurance born of conviction, yet he claims not infallibility. He has ever been unable to accept the usual explanations of the great physical forces; and the inadequacies of mooted theories have impelled him to efforts for more philosophical interpretations.

  • For thirty years or more the expressions “Correlation of the Physical Forces” and “The Conservation of Energy” have been common, yet few persons have taken the necessary pains to think out clearly what mechanical changes take place when one form of energy is transformed into another. Since Tyndall gave us his book called Heat as a Mode of Motion neither lecturers nor text-books have attempted to explain how all phenomena are the necessary outcome of the various forms of motion.

  • A vector is a quantity that possesses both magnitude and direction. Examples of vector quantities are displacement, velocity, acceleration, and force. A vector quantity can be represented by an arrow drawn to scale. The length of the arrow is proportional to the magnitude of the vector quantity. The direction of the arrow represents the direction of the vector quantity.physics in general is the most scientific study of "physical" and "interaction".

  • We Americans assume that our economic system will always scamper to provide us with the products we want. Special orders don’t upset us! I want my MTV! The truth is more complicated, especially in our education system, which is paid for by the students but controlled by the professoriate. Witness the perverse success of the bloated science textbook.

  • The field of molecular biophysics is introduced in the following pages. The presentation focuses on the simple underlying concepts and demonstrates them using a series of up to date applications. It is hoped that the approach will appeal to physical scientists who are confronted with biological questions for the first time as they become involved in the current biotechnological revolution. The field of biochemistry is vast and it is not the aim of this textbook to encompass the whole area.

  • We have developed a new formulation for fast calculation of far-field force of fast multipole method (FMM)in molecular dynamics simulations. FMM is a linear algorithm to calculate force for molecular dynamics simulations. GRAPE is a special-purpose computer dedicated to Coulombic force calculation. It runs 100-1000 times faster than normal computer at the same price. However FMM cannot be implemented directly on GRAPE. We have succeeded to implement FMM on GRAPE and developed a new formulation for far-field force calculation. ...

  • The vascular endothelium is exposed to an array of physical forces, includ-ing shear stress via blood flow, contact with other cells such as neighboring endothelial cells and leukocytes, and contact with the basement membrane. Endothelial cell morphology, protein expression, stiffness and cytoskeletal arrangement are all influenced by these mechanochemical forces.

  • When it comes to exercising, the problem with most people is that of taking time out from their busy schedules, lack of adequate gymnasium facilities and diversity of work assignments. This book was writen for Royal Canadian Air Force personnel, who needed to keep fit even from the confines of their barracks. The Five Basic Exercises (5BX) Plan presented in this booklet is designed to show you how to develop and hold a high level of physical fitness, regardless of who you are or where you may be located. The scheme is not dependent on elaborate facilites or equipment. The...

  • It is important to note that the metastatic cells do not float about in isolation; rather, they reside within the extra-cellular matrix (ECM) of the host organ. The ECM is a complex mesh of proteins that fill voids be- tween cells, and it participates in the development of both healthy and cancer cells through chemical and mechanical signalling. There is evidence that changes in the stiffness of the ECM affect the signalling and hence the progress of the cancer.

  • 21 Unit Two PHYSICS Physics is the major science dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. Sometimes in modern physics a more sophisticated approach is taken that incorporates elements of the three areas listed above; it relates to the laws of symmetry and conservation, such as those pertaining to energy, momentum, charge, and parity. Physics is closely related to the other natural sciences and, in a sense, encompasses them. ...

  • Toss your keys along the floor, they’ll skitter along for a bit as friction does negative work on them, reducing their kinetic. Quickly, the keys come to rest, and the kinetic energy you gave them is gone. But in this case they can’t turn around (as they did when you picked them up), gather speed from the same frictional force that acted to slow them, and jump back into your hand with the same kinetic energy. Once the motion stops, the friction stops, and it can not restore the kinetic energy of the keys as gravity is able to...

  • Perhaps nothing is so ingrained in our senses as the perpetual pulling of the earth on our surroundings. It’s always there, never changing. It’s been hugging solids, liquids and gases to the earth’s surface for over 4 billion years. Earth’s gravity is built into our descriptions of our world with words like up, down, and weight. Exactly what is weight? A weight is a force, nothing more. Your weight is the pull of earth’s gravity on your body. Likewise, the weight of your car is the force of the earth’s attraction for it. The greater the mass is, the...

  • Tools shape how we think; when the only tool you have is an axe, everything resembles a tree or a log. The rapid advances in instrumentation in the last decade, which allow us to measure and manipulate individual molecules and structures on the nanoscale, have caused a paradigm shift in the way we view molecular behavior and surfaces. The microscopic details underlying interfacial phenomena have customarily been inferred from in situ measurements of macroscopic quantities. Now we can see and “finger” physical and chemical processes at interfaces.

  • Industrial robots are currently employed in a large number of applications and are available with a wide range of configurations, drive systems, physical sizes and payloads. However, the numbers in service throughout the world are much less than predicted over twenty years ago (Engelberger 1980). This is despite major technological advances in related areas of computing and electronics, and the availability of fast, reliable and low-cost microprocessors and memory. This situation is mainly a result of historical and economic circumstances, rather than technical considerations.
